Configuration in Spring MVC configuration file
<!-- 设置使用注解的类所在的jar包,只加载controller类 --> <context:component-scan base-package="com.jay.plat.config.controller" />
<!-- 使用 Swagger Restful API文档时,添加此注解 --> <mvc:default-servlet-handler />
<mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/"/> <mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>
maven dependency
<!-- 构建Restful API --> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.4.0</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.4.0</version> </dependency>
Swagger configuration file

Configuration instructions:
@Configuration 配置注解,自动在本类上下文加载一些环境变量信息 @EnableWebMvc @EnableSwagger2 使swagger2生效 @ComponentScan("com.myapp.packages") 需要扫描的包路径
Use annotations in Controller Add API document
package com.jay.spring.boot.demo10.swagger2.controller; import java.util.ArrayList; import java.util.Collections; import java.util.HashMap; import java.util.List; import java.util.Map; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; import com.jay.spring.boot.demo10.swagger2.bean.User; import io.swagger.annotations.ApiImplicitParam; import io.swagger.annotations.ApiImplicitParams; import io.swagger.annotations.ApiOperation; @RestController @RequestMapping(value = "/users") // 通过这里配置使下面的映射都在/users下,可去除 public class UserController { static Map<Long, User> users = Collections.synchronizedMap(new HashMap<Long, User>()); @ApiOperation(value = "获取用户列表", notes = "") @RequestMapping(value = { "" }, method = RequestMethod.GET) public List<User> getUserList() { List<User> r = new ArrayList<User>(users.values()); return r; } @ApiOperation(value = "创建用户", notes = "根据User对象创建用户") @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User") @RequestMapping(value = "", method = RequestMethod.POST) public String postUser(@RequestBody User user) { users.put(user.getId(), user); return "success"; } @ApiOperation(value = "获取用户详细信息", notes = "根据url的id来获取用户详细信息") @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long") @RequestMapping(value = "/{id}", method = RequestMethod.GET) public User getUser(@PathVariable Long id) { return users.get(id); } @ApiOperation(value = "更新用户详细信息", notes = "根据url的id来指定更新对象,并根据传过来的user信息来更新用户详细信息") @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long"), @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User") }) @RequestMapping(value = "/{id}", method = RequestMethod.PUT) public String putUser(@PathVariable Long id, @RequestBody User user) { User u = users.get(id); u.setName(user.getName()); u.setAge(user.getAge()); users.put(id, u); return "success"; } @ApiOperation(value = "删除用户", notes = "根据url的id来指定删除对象") @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long") @RequestMapping(value = "/{id}", method = RequestMethod.DELETE) public String deleteUser(@PathVariable Long id) { users.remove(id); return "success"; } }
Effect display
Access path:
Restful API 访问路径: * http://IP:port/{context-path}/swagger-ui.html * eg:http://localhost:8080/jd-config-web/swagger-ui.html
